buy soil that is pre nuted. grow for 3-4 weeks then add nutes slowly. for the first week grow under 24hours of light then go down to 18/6. if your leaves ever turn yellow or start too add nutes. also make sure that your light is about 2-3 inches from your plant. if you go any farther it will stretch horribly and that will make your stem weak as hell. thats very important that you dnt forget that
Don't buy soil that is pre nuted. Get yourself a big bale of promix, that only has a small feeding, or none at all. This will fill a lot of pots. I get 2 bales a year.
As a beginer, I would get somthing like flora nova to use for nutes. Wait till you see 5 fully formed leaves before you add 1/4 strength flora nova grow. Feed every other watering, but slightly increase the dosage. 1/4 to 3/8 to 1/2. tsp. If you see any yellowing post a pic. Don't nute before we look at it. Keep ph of nutrient solution 6.5.
